SpectraDot™ Fluorescent Nanocrystals

Same Size & Mass for all Colors. More Colors. More Stable.

Unlike standard Quantum Dots, the color of our quantum dots is tuned by composition rather than size.

SpectraDOTs : Alloyed Nanocrystal Technology

Our Quantum Dots: are equivalent in size (5.5nm) and mass regardless of emission color. All colors are equally bright and have comparable quantum efficiency throughout the visible spectrum. Our Quantum Dots are inherently stable as single semiconductor nanocrystals.

Features:

Made from a composition tunable cadmium, selenium and sulfur core. The color is tuned by composition rather than size.

SpectraDOTs are equivalent in size (5.5 nm) and mass regardless of color, so all SD’s have equivalent effect on kinetics.

All colors are equally bright and have comparable quantum efficiencies throughout the visible spectrum.

SpectraDOTs are stable as single nanocrystals in solution (~ 10 nm hydration spheres).

Photostable (No bleaching) even under constant illumination.

Very sharp emission peaks with little to no cross talk.

Stable in most buffers (including phosphate) and up to 160 mm ionic strength.

Can be autoclaved.

Available in water soluble formats (carboxyl and amine surfaces) or organic soluble format (oleic acid surface).
